Specification of Letters Patent. Patented July 30, 1918.

Application filed March a1, 1917. Serial No. 158,986.

To all wkom'z't may concern:

Be it known that I, THEODORE S. ETH- BRIDGE, a citizen of the -United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certainnew and useful Improvements in Pamphlet-Covering Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as, will enable others skilled in the art to which it appertains to make and use the same.

This invention'relates to improvements in book covering devices and more particularly to a device to aid and expedite the customary hand process of vapplying glued covers to books, pamphlets and the like and its' object is to provide a device which will acconnnod'ate and operate upon books and covers of various dimensions and will effectivelyperform the operations of locating the book in its proper position relative to the cover and of affixing the cover to the book after the glue has been applied to the cover or the book.

In the art of bookbinding wherein the covers are afiixed to the. books by gluing them along the backportion of the book, a large part of the work has'been done heretof'ore by hand, this being necessarily slow and subject to inaccuracy of the operator. The device embodying this invention is adapted to greatly facilitate and expedite the hand method of affixing the cover to the book and has for its primary object and purpose the provision of novel means to this end.

The device is also provided with various useful features of construction and arrangement whereby it may be 'readilyadjusted to receiy e and operate upon books and covers varying in dimensions from the smallest to the largest customarily used as hereinafter more fully described and definitely pointed out in the claims. The preferred construction of this device is. shown in the accompanying drawings in which Figure 1. is a perspective view of a device embodying this invention showing a cover sheet and in their relative positionsat one point of the operation." I

fg- 2 Pl n ew .Qf h devi e o n Fig. 6 is a transverse section through a part of the device illustrating the manner" in which thecover is foldedover the back of the book.. V

Fig. 7 is a longitudinal sectional detail showing the .books engagement with the pressure roller. 7 v I Fig. 8 is a sectional detail of the adjilstable book guide and cover stop. V Fig. 9 is a plan view of the device showing a modification of thodoook guides gig. 10 is a side elevation of the same, an

Fig. 11 is a partial front elevation ofthe same.

Like numbers refer to like parts through.- out the different views of the drawing.

1 represents the table divided near its middle providingan elongated opening 2 extendin from front to rear of the device. The ta le is supported-by a frame 3 beneath it. The frame has an ,elongated'bed l extendinglongitudinally of the opening2, and

beneath the plane of the table 1' to serve as the bottom of. the" die. The. vertical sides 5 and 6 of the die are mounted upon the bed 4 and lie within the opening 2, extending the entire length of-the sa me'and projecting past the forward edge of; the table The inner vertical faces of th'esesides extend vertical curveddivergingly.- 5

The side 5 is slidably mounted upon the bed .4 being held in place by studs 7 passing through lugs 9 on the bed and having heads for a part of their width and .arethence 8 upon their outer ends which engage the lugs and limit the movement toward the side 6'. Springs 1-0'surrounding the studs 'engage'respeotively the side 5fand ithelu s 9 ieldably forcing the side 15 toward t e The die side 6 is slidably mounted upon the bed 4: and movable toward and from the side 5 being maintained in parallel relation thereto. For this purpose feet 11 are provided on the side 6 having slots 12 extending transversely of; the die and studs 13 attached to the bed extend through the slots 12 and traverse the same.

Studs 15 attached to and projecting from the under side of the feet extend through and traverse transverse slots 14 in the bed 4 and also extend through and traverse inclined cam slots 16 in a plate 17 longitudinally movable on the under side of the bed. The plate 17 is also provided with longitudinal slots 18, and studs 19 are attached to the under side of the bed and extend through the slots 18 causing the plate to travel in a true longitudinal direction. The plate 17 is actuated by a screw 20 engaging a threaded lug 21 on the plate and having a bearing in a lug 22 which projects from the bed and a knob 23 is provided on the outer end of the screw whereby it may be manually turned.

It will be seen that longitudinal movement of the plate 17 by means of the screw 20 causes the studs 15 to be moved transversely as they traverse the inclined cam slots 16, thus moving the die side 6, to the feet 11 of which the studs 15 are attached, toward or away from the opposite side 5 in parallel relation thereto.

As a back stop for the cover sheet 2 1 a bar 26 extends transversely across the entire width of the table in contact therewith being attached preferably by screws 27 so that it may be moved and attached at various positions on the table, it being desirable to locate it near the front for narrow books and near the back for wider ones. To adjust the cover sheet in lateral position a stop 28 is provided being adjustably mounted near one end of the bar 26 by means of a screw 29 extending through a slot 30 in the body of the stop. Various threaded holes 31 are provided in the bar 26 to receive the screw 29 and increase the range of adjustment of the stop 28.

The book 25 is guided into contact with the cover sheet by means of a back stop 32 extending vertically from the middle position of the bar 26 and by wings 33 and 34a divergingly from the forward face thereof.

The back stop 32 is clamped to the bar 26 by the screw 35 which extends through a slot 36 in the base of the back stop. This stop may be adjusted so that its vertical face will come flush with the edge of the bar 26 which forms a stop for the cover sheet or it may be extended beyond the edge of said bar as shown in Fig. 8 when it is desirable to have the cover overhang the edge 'of the book. The wing 33 is fixed to the stop 32 so that its vertical face will stand in alinement with the inner face of the die side 5 when said side is in normal position. The wing 3 1- is slidably mounted on the stop 32 and clamped by the screw 37 extending through the slot 38 in said stop and may be adjusted to aline with the die side 6 as said side is adjusted to accommodate books of various thicknesses.

Elongated guides 33 and 3 1 as shown in Figs. 9, 10 and 11 may be substituted for 33 and 34;. These elongated guides serve to guide the book more accurately to contact with the cover sheet. One of these guides such as 33 may be omitted entirely in which case the remaining one serves as a stop'to engage one side of the book and thus guide it to its proper location. Beneath the forward projecting ends of the die sides 5 and 6 a pressure roller 39 is located to engage the back of the covered book as it is drawn from the device. This roller extends transversely of the die and is located with the upper part of its periphery slightly above the plane of the bed 1. It is preferably provided with a resilient face such as rubher or felt and is freely rotatable on'its axis 40, being journaled in extensions 41 on the base 1.

Flat springs 42 are attached in recesses &3 near the forward ends of the inner faces of the die sides 5 and 6 and their free'ends normally project beyond the faces of the die sides above the roller 39. These jaws exert an additional lateral pressure upon the sides of the covered book near the back thereof as it is being drawn over the roller 39.

In operating this device the glue is first applied either to the back of the book 25 or to a portion 24 of thecover sheet-24: and the cover sheet is then placed upon the table 1 and located by the bar 26 and lateral stop 28 so that the portion 24 which is to come adjacent and be glued to the back of the book, will lie over the opening in the die and beneath the guide wings 33 and 34.

The book is then held vertically with its rear end against the stop 32 and between the guide wings 33 and 345, its forward end being guided by hand, and it is brought into engagement with the cover sheet and forced downward into the die carrying the cover sheet; with and by the spring pressure of the side 5 of the die and friction of the cover sheet between the two sides 5 and 6 the back of the book is squeezed tightly together and the cover stretched tightly over it and folded evenly over the corners. The book and cover are then moved longitudinally from the die, the back riding over the roller 39, thereby causing the cover to be pressed snugly against the back, the springs 12 at 7 The springs 12 are especially desirable Where the cover is glued, not only to the back of the book but also to narrow portions of the sides near the back as is often done.
